Palmer Dabbelt 4f7799d96e genirq/irqchip: Remove MULTI_IRQ_HANDLER as it's now obselete
Now that every user of MULTI_IRQ_HANDLER has been convereted over to use
GENERIC_IRQ_MULTI_HANDLER remove the references to MULTI_IRQ_HANDLER.

bool "Support sparse irq numbering" if MAY_HAVE_SPARSE_IRQ
---help---
Sparse irq numbering is useful for distro kernels that want
to define a high CONFIG_NR_CPUS value but still want to have
low kernel memory footprint on smaller machines.
( Sparse irqs can also be beneficial on NUMA boxes, as they spread
out the interrupt descriptors in a more NUMA-friendly way. )
If you don't know what to do here, say N.
config GENERIC_IRQ_DEBUGFS
bool "Expose irq internals in debugfs"
depends on DEBUG_FS
default n
---help---
Exposes internal state information through debugfs. Mostly for
developers and debugging of hard to diagnose interrupt problems.
If you don't know what to do here, say N.
endmenu
config GENERIC_IRQ_MULTI_HANDLER

help
Allow to specify the low level IRQ handler at run time.
